MAC values for Halothane Enflurane Isoflurane Desflurane Sevoflurane Nitrous oxide

Halothane-0.75 Enflurane-1.68 (1.7) Isoflurane-1.15 (1.2) Desflurane-6 Sevoflurane-2.1 Nitrous oxide-105

2

Blood/Gas of Halothane Enflurane Isoflurane Desflurane Sevoflurane Nitrous oxide

Halothane-2.4 Enflurane-1.9 Isoflurane-1.4 Desflurane-0.42 Sevoflurane-0.7 Nitrous oxide-0.46

3

Vapor pressure of Halothane Enflurane Isoflurane Desflurane Sevoflurane Nitrous oxide

Halothane-244 Enflurane-171 Isoflurane-239 Desflurane-669 Sevoflurane-170 Nitrous oxide-39,000

4

Metabolism of Halothane Enflurane Isoflurane Desflurane Sevoflurane Nitrous oxide

Halothane- 20% Enflurane-2% Isoflurane-0.2% Desflurane-0.02% Sevoflurane-2-5% Nitrous oxide-0.04%

5

what 2 VAA are not stabile in soda lime

halothane sevoflurane

6

Halothane MAC Blood/gas Vapor pressor metabolism Soda lime stabibility

MAC-0,75 Blood/gas-2.4 VP- 244 Met-20% Soda lime stabibility- no

7

what is halothane best used for

inhalation induction

8

what is the major SE of halothane

myocardial depression

9

what inhalation agent is an isomer of Isoflurane

enflurane

10

Enflurane is associaed with what SE

Seizures

11

Isoflurane MAC Blood/gas Vapor pressure Metabolism Soda lime stabibility

MAC-1.15 (1.2) Blood/gas-1.4 Vapor pressure-239 Metabolism-0.2% Soda lime stabibility-yes * remember it wants to be one two (1.2) it's an isomer. so: MAC 1.2 VP=2(39) Met= (0.)2

12

Desflurane MAC Blood/gas Vapor pressure Metabolism Soda lime stabibility

MAC-6 Blood/gas- 0.42 Vapor pressure-669 Metabolism-0.02% Soda lime stabibility-yes * remember DES=6 so: MAC 6 VP=66(9) B/G=0.42 (4+2=6)

13

Sevoflurane MAC Blood/gas Vapor pressure Metabolism Soda lime stabibility

MAC-2.1 Blood/gas-0.7 Vapor pressure-170 Metabolism-2-5% Soda lime stabibility-No *how to remember SEVO=7 so: B/G-(0.)7 VP (1)7(0) Met=2-5% (2+5=7)

14

N20 MAC Blood/gas Vapor pressure Metabolism Soda lime stabibility

MAC- 105 Blood/gas- 0.46 Vapor pressure- 39,000 Metabolism-0.04% Soda lime stabibility- yes *how to remember N20>100 so: MAC=105 (>100) B/G= (0.)46 (4+6=10(0))

15

All inhalation agents are skeletal muscle relaxants EXCEPT for which one(s)

N20

16

What do all inhalation agents do to renal, with the exception of one, what doesthat one do, and which one is it?

all-decrease renal blood floe, GFR, and UOP -except for SEVO-it has high output renal failure

17

what is the only inorganic inhalation gas

N20

18

Which inhalation agent is a halonengated Alkane

Halothane

19

What can Halothane cause

Halothane Hepititis

20

Which inhalation agent is least expensive VAA, and is used all over the world

Halothane

21

Alkane substances such as soda lime can degrade what VAA?? and cause what toxicity?

-SEVO -Compound A

22

Prolonged exposure to N20 can cause what problem

Bone marrow depression -megoblastic anemia -pernicous anemia Neurological deficits -periphreal neuropathies

23

Which inhalation agent is halogenated with fluride, non pungent, and rapid increase in Alveolar concentration makes it a great choice for inhalation induction

SEVO

24

Which is the least potent Inhalation agent

N20

25

Which inhalation agent is gas at room temp and ambiant pressure, and is able to be stored as a liquid under pressure?

N20

26

All inhalation agents decease B/P, what is the difference b/t halothane and the rest

Halothane decreases myocardial contractility and all others decrease SVR

27
